In the early 1900’s, desert sand was commonly used as a building material because of its high water absorption capability. Although sand has excellent fire retardant properties, there are limitations to the usefulness of sand as a thermal conductor or insulation product, and even though many engineers consider it to have these properties, it is unable to absorb enough heat to do any good in construction projects. For this reason, sand is not often used as a building material in modern day, continue learning.
The other major limitation of sand as a construction material is that it lacks elasticity. Sand is incapable of stretching to any large degree; therefore, once you begin construction with sand, you must stop the use of the land before the project is completed. The large amounts of sand used in projects also mean that there are often many smaller, more inflexible joints to deal with, as well as cross ties and trusses. Sand also cracks extremely easy, making cracks a major safety issue for buildings in desert areas. Finally, the lack of flexibility means that there is a very high likelihood of the structure failing due to repeated flexing and stretching.
Although sand is not used for construction, it has many positive benefits as a landscaping product. Sand can easily be used to help define a landscape, by using it to create dunes, and by using it to help plants grow. Another benefit of using sand as a landscaping product is that it is so lightweight, it can be used to transport equipment and supplies over long distances without any noticeable negative effects on the ground. Finally, the ease with which sand can be moved makes it ideal for construction projects. In short, sand is a great landscaping product, but it does have its limitations.
